Just when you think cybercriminals have exhausted their bag of tricks, they come up with new and inventive scams. Their latest tactic involves faking data breaches to steal money from unsuspecting business owners and dark web data buyers.
Earlier this year, Europcar, a global car rental company based in France, discovered that a cybercriminal was selling what appeared to be private information about its 50 million+ customers on the dark web. The company promptly launched a formal investigation, only to find out that the data being sold was fake. It was likely generated using advanced tools like generative AI.
How Are They Doing It?
Using AI-powered tools such as ChatGPT, cybercriminals can swiftly create realistic-looking data sets. These savvy criminals conduct thorough research to design data sets that appear complete, featuring correctly formatted names, addresses, emails, and even local phone numbers. They also exploit online data generators, typically used for software testing, to produce large, authentic-looking data sets. Once they have these fabricated data sets, hackers select a target company and post the fake information on the dark web, claiming it was stolen.
Why Are They Doing It?
Why would hackers fake a data breach? There are several reasons, beyond the obvious benefit of avoiding the labor-intensive task of breaching a network's security.
- Creating Distractions: One effective way to lower a company's defenses is to divert its attention to a supposed breach. The company becomes so focused on identifying the breach that it may overlook other vulnerabilities.
- Bolstering Their Reputation: Reputation is crucial in the hacker community. Targeting a well-known brand publicly can earn them notoriety and recognition from other hacker groups.
- Manipulating Stock Prices: For publicly traded companies, a data breach can lead to a rapid decline in stock prices, often between 3% to 5% or more. This panic can be exploited by cybercriminals for financial gain.
- Learning Security Systems: Faking a data breach allows cybercriminals to gain insights into a company's security measures, including how they prevent, detect, and resolve attacks. Understanding these processes helps hackers refine their strategies for future attacks.
Why Is This Bad for Businesses If the Data Is Fake?
By the time the public learns that the data is fake, the damage is usually done. For instance, in September 2023, Sony was targeted by a ransomware group that falsely claimed to have breached the company's network and acquired its data. The news spread quickly, tarnishing Sony's reputation, and by the time the investigation revealed the claims were false, the damage to their brand was already significant.
What Can You Do to Prevent Fake Data Breaches?
To avoid falling victim to a fake data breach, consider these steps:
- Actively Monitor the Dark Web: Ensure that you or your cybersecurity team routinely monitor the dark web. If you find someone selling your data, investigate the claim immediately to mitigate potential damage.
- Have a Disaster Recovery Plan in Place: Develop a communication plan in advance to guide your team on how to respond if a data breach occurs. This plan should be refined as needed.
- Work with a Qualified Professional: Focus on your core business activities and leave IT-related issues to the experts. Partnering with a cybersecurity professional can help you identify, resolve, and prevent breaches, ensuring that steps #1 and #2 are effectively managed and giving you peace of mind.
